🎧PODCAST🎧: Is it really worth growing F2 canola seed?
GOA’s @MaurieStreet & @pennyheuston chat about growing F2 canola seed.

❓Does it save you money OR cost you yield❓

…based on trial work GOA done across the Central West into farmer-retained hybrid seed.

@agrobaz @nicolebtweets @NSW_AGRONOMY @GRDCNorth Baking paper - that’s a great idea Baz✅. I’ll give it a go

[Colin McMaster @Master4Colin]

Been getting some enquires about the paper roll seed vigor test.

Here’s a quick video on the procedure.@NSW_AGRONOMY @GRDCNorth

Hope it helps

[Colin McMaster @Master4Colin]

@QuentenKnight Hi Quenten - we have only been using it on canola…but can’t see why it wouldn’t work on the other crop types.

[Colin McMaster @Master4Colin]

Well done baz 👏 - its a cracking little test

[Barry Haskins @agrobaz]

Hats off to @Master4Colin for this little germ test plan. Wet paper towel, put seed in a row along centre, roll up towel like a cigar, wrap in foil leaving top open for air and stand it upright. Look at both shoot and root for normality.

**Parkes canola field walk - 9 October**

Hope to see you next week to inspect the Canola NVT trial site with @HertelKathi and to discuss the latest @theGRDC canola establishment research results.

Great day at Tottenham yesterday, and thanks @GRDCNorth for the opportunity to present.

For anybody interested, there’s also a new @theGRDC funded App developed by @CSIRO called ‘Summer weed tool’…worth checking out this summer.

[GRDC North @GRDCNorth]

Weeds are a red card for fallow management - @Master4Colin looks at the cost of uncontrolled weeds to system profit – a nitrogen & water story. #GRDCUpdates #Tottenham

@DaveFinlayTrang @theGRDC @AgroJAK Pleasure Dave - thanks for sharing with the group what you’re up to. Love your ‘out of the box’ thinking and will be following your work with great interest.

[Colin McMaster @Master4Colin]

Big thanks to the growers and advisors for supporting yesterdays @theGRDC canola establishment field walk at Canowindra.

Great discussion and thanks to @AgroJAK and @DaveFinlayTrang for your contribution👍. Hope it helped

[Colin McMaster @Master4Colin]

@davelangfield75 @AgroJAK No probs at all Dave 👍. Will keep you posted on the results.

[Colin McMaster @Master4Colin]

@theGRDC Canola establishment field walk tomorrow at Canowindra.

Time: 10am
Location: Woodlands (refer to flyer)

Rainout shelters have provided some great insights into dry sowing and the critical moist% required for establishment. Hope to see you there. @CSIRO @NSW_AGRONOMY

[Colin McMaster @Master4Colin]

Be great to see you @theGRDC canola establishment field walk at Canowindra on Friday 13 June.

Strong focus on the critical soil moisture requirements for est % & the various implications of stubble, seed depth, soil strength & seedbed moist dry-down. @CSIRO @NSW_AGRONOMY

[Colin McMaster @Master4Colin]

@grassrootsag @AgroJAK @MckinleyMatt @theGRDC @NSW_AGRONOMY @MathewDunn19 @tony_swan64 @Farm_Link @JessicaZieltjes Just finished setting up irrigation yesterday at Condo. Will start applying various water treatments on Monday. Will keep you posted 👍

[Colin McMaster @Master4Colin]

Great morning by the Grassroots Agronomy team and a massive thanks for the opportunity to present @theGRDC canola establishment results 👍. @CSIRO @NSW_AGRONOMY

[Grassroots Agronomy @grassrootsag]

Top session in Marrar for our 2025 grassrootsag preseason.

Lee Hudek @newedgemicrobes with a preso + live demo on inoc. pulses. @Master4Colin best bet canola estab. & Claudia Mitchell (thecapacityco) on effective farm teams.

Big thanks to @JessicaZieltjes for organising.

[Colin McMaster @Master4Colin]

@lawbal44 @theGRDC @CSIRO @NSW_AGRONOMY @AndrewF00370433 @AgroJAK @agrobaz @MaurieStreet @brill_ag @GRDCNorth Hi Lawrence - trial sites are at Canowindra and Condo. The Canowindra site is up mulligans rd at Woodlands (thanks @RobGindurra). Will keep you posted

[Colin McMaster @Master4Colin]

Using shelters & irrigation to adjust seedbed moisture & to ensure dry conditions post sowing.

Questions are: what’s the critical moist % to establish canola, & can seed be placed deeper if surface too dry? Really looking foward to these @theGRDC results👍@CSIRO @NSW_AGRONOMY

[Phil Cranney @PhilCranney]

Cracking’ morning for a BBQ brekkie at Greenethorpe, see you there @Master4Colin @AgroJAK @grassrootsag @wrightim1 @GRDCNorth @NSW_AGRONOMY
